Dear maintainer, thanks for your work with this package, really appreciated.

java: ../../src/xcb_io.c:730: _XReply: Assertion `!xcb_xlib_threads_sequence_lost' failed.
Aborted

What I did was:
 * open pdfsam
 * click on "merge" documents option
 * load 2 documets
 * click "Run" at the bottom
 * click "Open" at the bottom after the run was completed.
 * the program crashed.

Please note, the merged PDF document was generated despite the crash.

regards.
